Robert Millar (born 13 September 1958) is a Scottish former professional road racing cyclist.
Millar won the "King of the Mountains" competition in the 1984 Tour de France and finished fourth overall. Millar was the first rider from an English speaking country to have won the Mountains classification in the Tour de France. This success was the first time a British rider won a major Tour classification, and was unsurpassed as the highest Tour finish for a Briton until Bradley Wiggins was retrospectively placed third in the 2009 Tour de France. He is one of only five Britons to have won a Tour de France jersey competition along with Wiggins, Chris Froome, Mark Cavendish and Adam Yates. He rode the Tour de France eleven times completing the race eight times.
Millar also achieved the highest finish by a Briton in the Giro d'Italia, finishing second in 1987 and also winning the King of the Mountains classification. As well as the Giro second-place finish, he finished second in two other Grand Tours: the 1985 and 1986 Vuelta a España. Millar was the first British rider to achieve three top three finishes in grand tours (an achievement only equalled when Wiggins was promoted to third in the 2009 Tour de France in 2012). He was set to win the 1985 Vuelta before losing the leader's jersey on the penultimate stage due to collusion by the Spanish-speaking teams.
Millar won the 1985 Volta a Catalunya, the 1989 Tour of Britain and the 1990 Dauphiné Libéré.
